The 2012 Igem Team form the TU Munich created a new form of yeast, that, additionally to it's regular use in beer brewing, is able to also produce caffeine. Thus, when you switch on the light while brewing beer, the yeast adds caffeine. As an additional feature, you can change the type of light and the yeast starts producing "Radler", a beer with less alcohol and additional lemon taste.
